Got an issue on Linux too (Ubuntu 18.04.03 LTS) See attached screenshot. Does the final .9 in the installed library matter?

Hi, I am pretty flexible on time these days, except for next Friday afternoon/night and next Saturday (at GMT - 5). I already contacted the organizers to let them know that you may will be giving the talk (I talked about that possibility while applying). We can coordinate off-list. Just let me know your availability so we can figure out all details. Last version install instructions are here: https://mutabit.com/repos.fossil/grafoscopio/doc/tip/readme.md.html Cheers, Offray On 14/01/20 10:00 a.Â m., phil(a)highoctane.be wrote: > Can help too. > > Need correct version to demo as what I do have is old. > > Phil > > On Tue, 14 Jan 2020, 13:49 Santiago Bragagnolo, > <santiagobragagnolo(a)gmail.com <mailto:santiagobragagnolo@gmail.com>> > wrote: > > I am in.

Re: [Pharo-users] Pharo on OpenSUSE (FFI / libgit2 errors)

by Jan BlizniÄenko

The VM crash for Launcher is not caused by having different VM, but by using specific usage of SSL lib that does not work with this workaround.

Re: [Pharo-users] Floating point arithmetic

by Bruce O'Neel

HI, I would upgrade that "a good read" to a critical read if you do anything with floating point. Â Floating point numbers are not real numbers but rather a small subset, and, have all kinds of funny properties. But we use them just like real numbers and that's what catches us out. cheers bruce > On Sun, Jan 12, 2020 at 02:13:00PM -0600, Donald Howard wrote: > > "What are other suggestions, workarounds or approaches community has?" > > This is a good read on the subject: > > https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html > > Title is "What every computer scientist should know about floating point arithmetic". > > Pierce

Re: [Pharo-users] Pharo on OpenSUSE (FFI / libgit2 errors)

by Jan BlizniÄenko

Thank you for forwarding this. At first, I though "well, that is the same solution I posted in previous mail/post, you just have libs in different directory", but it is not. It creates link just once in lib64, not in each VM, which is way better (but has be done by root). Unfortunately, it does not work for Pharo Launcher on OpenSUSE - causes segfaults, don't know why. Usual VM is OK. Jan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Arkaitzmugica posted this on discord, which worked for him. Since the problems were similar, that may be relevant for you (or other people) 12:28 AM/]/arkaitzmugica/:/ I've made Pharo work on Fedora 31. First libgit2-devel must be installed. Then sudo ln -s /lib64/libcurl.so.4 /lib64/libcurl-gnutls.so.4 And the last step is following the instructions related with some security parameters: you must create a file, /etc/security/limits.d/pharo.conf cat pharo.conf * hard rtprio 2 * soft rtprio 2 Reboot, and pharo works fine. /[/12:32 AM/]/arkaitzmugica/:/ If working with 'toolbox' command line tool, like me, because I'm using Fedora 31 Silverblue, you should keep this in mind too when creating a container with a custom Dockerfile. /[/12:34 AM/]/arkaitzmugica/:/ I haven't tested, but I think it could work also for Centos and RHEL.

Re: [Pharo-users] As promised, the sequel!

by horrido

Thanks, Ted. Yes, I chose red for the Tesla because it complements the blue I chose for the Maserati. You see, everything I do has a reason. I was also wondering what other technologies have undergone a revival. To be honest, it's hard to come up with anything. (Even the Buratino rocket launcher fits in with this motif. Three vehicles, all with a similar visual orientation.) I suppose I could cite Objective-C as an example. In the late 1980s, it was chosen by Steve Jobs' NeXT company for developing their software. As we all know, NeXT ultimately failed and along with it, Objective-C. Many years later, Apple's iPhone made Objective-C the darling of the IT world. This was a tremendous revival. The problem with this story is that NeXT/Objective-C was never /really/ that popular to begin with. Maybe I can cite the audio turntable. It was once very popular. Then it died with the arrival of the CD. In recent years, vinyl records have again found a following. tbrunz wrote > Thanks, xap! Great sequel, Richard.
